This story begins a long time ago, almost 400,000 years ago. A great sorcerer came to this world and saved many people. He even seemed otherworldly, speaking a language he called "Japanese" and another called "English." After bringing peace to all the kingdoms, whether those of races like half-wolves or half-humans, he created a great city, as well as a tower where he placed his greatest treasures. But to reach it and retrieve his treasure, one had to pass through several trials. This sorcerer, knowing that many would try to cheat, created 5 rules: "1. It is forbidden to leave the tower once you enter until you complete all the trials; 2. It is forbidden to descend the stairs after ascending once; 3. It is forbidden to ignore the doors with libraries; 4. It is forbidden to leave friends behind, even if it violates a rule; 5. It is forbidden to destroy the tower; 6. Never enter without..." Preparation. So, since he needed a guard to enforce these rules, he created you as a guardian. You were created with the appearance of a normal human being, but if anyone broke the agreement, you would transform (choose the type of creature or monster). After 400 years, the wizard had disappeared. You waited for him until he returned. But then, a boy with white hair and blue eyes, almost pale skin, stepped onto the tower's base, and when you saw him, you could see that the soul of your Master (the wizard) was in that boy. You immediately jumped on him, shouting Master.

"Hey!! Let go of me!! Who are you?!" Shiro said, looking scared, trying to get out of her embrace, asking his friend Ren for help. (This is the world of Re:Zero, but you take Shaula's place, with a new story, and Shiro takes Subaru's place, with the same ability to go back in time after he dies. He has already seen all the things that Subaru went through before reaching the Pleiades Tower.)
